FEATHERING PADDLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 410,148, dated September 3, 1889.

Application filed November 3, 1887. Serial No. 254,182. (ModeL) To all whom it may concern.-

Be it known thatI, AMos H. CARPENTER, of Waterford, in the county of Caledonia, State of Vermont, have invented a certain new and useful Improvement in Paddle and other Wheels, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is an isometrical perspective view representing my improved wheel mounted on the shaft; Fig. 2, an enlarged perspective view of the sleeve detached; Fig. 3, an enlarged top plan view of the cam and its clasp detached; Fig. 4, an enlarged view of one of the bracejoints; Fig. 5, an enlarged top plan view of the shifting-fork detached; Fig. 6, a side elevation of the same; Fig. 7, elevations showing certain details of construction; Fig. 8, an elevation showing two of the floats or blades and their connecting-rods detached, and-Fig. 9 a side elevation showing a modification of the improvement.

Like letters and figures of reference indicate corresponding parts in the different figures of the drawings.

My invention relates especially to feathering paddle and other wheels; and it consists in a novel construction and arrangement of parts, as hereinafter more fully set forth and claimed, the object being to produce a more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the main shaft; 13, the box or bearin gin which the shaft is mounted; O, the sleeve, and D the floats or blades.

The floats are arranged in pairs, the n1embers of each pair being disposed at right angles to each other and connected by a shaft E, which is bent at its center into the semicircular curve f. The shaft A is provided with a hollow boss G, in which the shafts E are journaled, said last-named shafts being arranged at right angles to each other and also curved portions f are within said boss. The outer ends of the floats D are provided with centrally-arranged studs a: and connected by to the shaft A, and so disposed that their qu adricircular braces H, the ends of the braces being halved and overlapping each pther, as shown in Fig. 4, and the studs ac jonrnaled in holes 472 formed therein; but the braces may be made semicircular, or may be unitedinone piece, if preferred.

The box B is designed to be supported permanently in any suitable manner, and is provided with lateral projections 25 on either side.

Arranged in parallelism with the shaft A, and fitted to slide longitudinally in the projections I, there are rods J P, adapted to engage a flange or projection c on the sleeve 0, said sleeve being disposed on the shaft A between the boss G and box B, and fitted loosely to said shaft. A fork K is placed astride the box B, its ends i being inserted in slots 0", cut in the rods J.

A vertically arranged bifurcated rod L is jointed to the fork K, said rod being designed to be journaled in suitable bearings, so that when partially rotated in either direction the rods J P will be moved into or out of position to engage the projection e on the sleeve 0 when said sleeve is partially rotated, as hereinafter described.

A clasp M is secured firmly to the sleeve and rendered adjustable thereon by the nut and bolt 12, said clasp being provided with an arm y, to which is secured a curved or camshaped bar N. This bar stands approximately at right angles to the shaft A and partially in the path of the floats D, so that when said shaft is revolved the edges of the floats adjacent to the sleeve 0 will be brought into contact with the laterally-curved port-ion g of said bar.

In the use of my improvement the shaft A is revolved in the direction of its arrow, and when one of the floats D strikes the cam-bar N, as described, the sleeve 0 will be revolved on said shaft until its projection '11 strikes the end of the rod J and stops the advance of said bar. The float continuing to revolve with the shaft A, and the cam-bar N being now stationary, the shaft E, on which the float is mounted, will be turned in its bearings in the boss G one-quarter of arevolution, thereby n feathering the float which is in contact with said bar, or bringing it into position at right angles to the shaftA and its companion float into working position or in parallelism with the shaft A, the floats being successively brought into contact with the cam-bar as said shaft revolves, and feathered in a manner that will be readily understood by all con versant with such matters without a more explicit description. If, now, it is desired to reverse the action of the floats, the rod L is revolved to withdraw the rod J and push forward the rod P, thereby permitting the sleeve C to be revolved by the float in contact with the bar N until the projection 41 passes the center and strikes the'projecling end of the rod P, whereupon the floats will be feathered, substantially as before described, but upon the opposite side of the shaft A, thereby reversing the action of the wheel without reversing the movement of the main shaft.

The shafts E, on which the floats are mounted, are prevented from revolving too far in either direction by the curved central portions f within the boss G, the curve of one shaft striking the straight portion of the other and stopping its revolutions, as shown by the dotted lines in Fig. 8, thereby rendering it unnecessary to provide stops for the floats on the exterior of said boss. When one of the floats strikes the curved portion g of the cambar N and is feathered as the main shaft revolves, it will be obvious that the companion float on the same float-shaft will be brought into working position and will be kept in working position by the straight portion of said cam-bar until the feathered float in contact therewith has passed the same.

In Fig. 9 my improvement is represented as applied to a windmill; but as I propose to make the same the subject-matter of another application for Letters Patent, the device shown in said figure is not claimed, broadly, herein.

I do not confine myself to mounting the rods J Pin the box B, as they may be mounted in any suitable manner if so arranged as to properly engage the projection t on the sleeve. Neither do I confine myself to adjustably securing the cam'N to the sleeve 0, as the cam may be formed integral therewith, if preferred; nor to the use of the rod L and fork K for actuating the rods J P, as any suitable means for that purpose may be employed; nor to the use of the braces II, as these may be omitted, if desired.

Having thus explained my invention, wha I claim is 1. In a feathering paddle or other wheel,

the shaft A, provided with the hollow boss G, in combination with the shafts E, carrying the floats D and provided with the curved portions f, said float-shafts being journaled in said boss at right angles to each other and their curved portions disposed within said boss, the members of each pair of said floats being arranged at right angles to each other, substantially as described.

2. In a feathering paddle or other wheel, the quadricircular braces H, in combination with the feathering-floats .D, provided with the studs 00, substantially as set forth.

3. The sliding rods J P, in combination with the box B, fork K, rod L, and sleeve C, mounted on the shaft A'and provided with the projection o, substantially as described.

4. The cambar N, in combination with the sleeve 0, provided with the projection 4;, said bar being adjustable on said sleeve, substantially as set forth.

5. The floatsI), mounted at right angles to each other 011 the shaft E, having the curve f, said shafts being journaled in the hollow boss G, in combination with the shaft A, means for feathering said floats, and means for reversing the floats, substantially as described.

6. The clasp M, provided with the arm y, and bolt and nut Z), in combination with the cam-bar N and sleeve 0, provided with the projection o, substantially as set forth.

7. In a device of the character described, the combination of the following instrumentalities, to wit: a main shaft, a box or bearing for said shaft, a hollov boss connected with said shaft, a sleeve mounted on said shaft and provided with a projection, movable rods adapted to engage said projection at opposite sides of said main shaft and serve as stops for said sleeve, a fork and rod or equivalent means for actuating said rods, two shafts curved at their centers and carrying floats at their outer ends, said float-shafts being j ournaled at right angles in said boss and having their curved portions disposed therein, and a cam mounted on said sleeve and adapted to engage said floats and feather them as the main shaft revolves, substantially as described.

8. In a feathering paddle or other wheel, the feathering-floats D, pivoted at theirouter ends to a connecting brace or braces, substantially as described.
